DISCHARGE APPLIANCE FOR CONTAINERS.

Application filed April 4,

To all whom it may concern:

Be it known that I, ALBERT E. NEELY, a

citizen or therUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Discharge Appliances for Containers, of which the following is aspecification. I

My invention aims to provide improved pouring constructions for permitting an efficient and convenient delivery or discharge of the contents of a container, such for 6X' ample as the pouring of salt, sugar, cereals, etc., from their packages.

One purpose of the invention is the pro-' duction of an appliance of this kind which will reliably and securely close the discharge opening or port except when it is desired or intended to pour out the salt or other similar product, which may be easily and readily moved to open and close the delivery aperture, which cannot ordinarily be unintentionally shifted out of proper or desired position, which is simple in structure and easily worked, and which is relatively inexpensive to produce.

An additional or auxiliary object of the invention is the provision of an appliance of the type specified in which the issuance or flow of the contents of the container there from may be readily governed and controlled, desirably by making at least a portion of the discharge port tapered and permitting it to be opened varying amounts depending upon the delivery flow required.

To enable those skilled in this art to have a full and complete understanding of the invention and its several'structural and functional advantages, I have illustrated in the accompanying drawing forming a part of this specification a preferred and desirable embodiment of the same, like reference characters designating the same parts throughout the several views.

In this drawing:

Figure 1 is a fragmentary perspective View of a portion of a package or container equipped with the novel pouring structure embodying the present invention;

Figure 2 is a face View of the same with the discharge aperture closed as it is in Fig ure 1; A

Figure 3 is a fragmentary view similar to 1921. serial No. 458,398.

that of Figure 2 with the discharge port open;

' Figure 4 is a partial section in a plane at the outer surface of the container wall having the'pouring hole; t i

Figure 5 illustrates in cross-section the manner of applying the slide-or valve to the delivery aperture; and

Figure 6 shows similarly the completed slide in place. i I

Referring now to the drawing, for the details of the construction, it will be observed that the round end wall or top 10 of the pasteboard or similar cylindrical container 11 is supplied near its'edge with a radiallydisposed, elongated aperture 12 therethrou h, such orifice havingparallel edges'13, 13 or a portion of its length, the edges 14:, 14 then converging forming a tapered or graduated perforation near the side wall of the receptacle. i

The purpose or object of using a flaring opening is to permit a graduated or regulated delivery or flow of the contents of the receptacle usually in granular or similar form.

Such opening or hole is adapted to be opened and'closed by a practically-fiat, metallic slide or closure 15, or one ofo-ther appropriate material, adapted to rest or bear on the plane outer face of the'wall 10.

The sheet-metal member, originally of substantially rectangular shape, is of general 1 form as viewed from the outside and comprises'a flat, narrower, middle section 16' of practically the same width asthe hole 13 uniting wider, plane, end portions 17 and 18 hearing flat against the outer face of the wall 10 and of greater width than the aperture 12, whereby when the slide is'in position to closethe pouringhole the side wings or edges of such end sections extend or project sidewise laterally beyond the intermediate portion 16, overlying or covering and bearing on the outer face of the portions of the end wall forming the side margins of the aperture, and, therefore, forming guiding and confining ears or wings coacting with the end wall of the container.

The metal at the two opposite sides of the middle or interjacent section 16 is bent down at 19, 19 and extends throu h and in contact with the parallel edges 13 3 of the aperture may be required, and the contents of the receptacle poured out or caused to issue 1n 12, being then bent or folded outwardly in opposite directions forming flanges or ears 20, 20 underlying and bearing on the bottom or inner face of the portions of; theend wall and end. wall,-the former is held against unintentional displacement, but is capable of being easilytslid to open orclose the hole when desired.

As is clearly illustrated, the slide or closure isof sutficient'length to enable it to completely close or cover the hole, as shown in Figures 1 and 2', but, when it is pushed back, as indicated in Figure 3, the tapering or converging discharge or delivery part of the aperture is uncovered more or-less as astream of a volume dependent 'upon the degree of uncovering of the opening, the

container, of course,- being tilted to effect such discharge of its contents.

.the receptacle.

hen the container equipped withsuoh pouring applianceis first-sent out in the trade, alabel may be-pasted over the slide if preferred to: insure that the opening will not be uncovered by. undesigned movement of the slide, but the use of such label :may

be dispensed with if feasible.

1 It'should be noted that the contents of the package by their outward pressure cannot accidentally open the closed aperturecontainer. and may be easily moved to desired position, but owing to the friction between the parts there is no substantial 1 danger ofsuch member changing position unintentionally.

Furthermore, the manufacture of such elementand its application to the container may be effected economically because such sheet-metal member is originally of rectani gularform and no waste of metal occurs in its production and the application of such valve element to the container may be accomplished with facility and with the simple operation of bending over'the wings or flanges against the under side of the cover or end wall.

When the slide or valve is pushed back to uncover or open the tapered delivery orifice,

the ends of those portions thereof in the aperture engage the wall at the inner end of the hole and limit or restrict the degree of opening movement of such valve.

Similarly, when the valve or. slide is moved outwardly to close the opening, its

movement is stopped when the hole is fully covered by the engagement of the other ends of those portions of the valve in theorifice coming in contact with the beginning of the tapered walls thereof or as is preferable small shoulders 21 are provided at the junction of the straight and tapered walls to act as. stops or abutments for suchparts of the slide.

Those skilled in this art will understand that the invention is not limited and restricted'to the precise and exactstructure 1 .Then the cover orslide may be pushed* .'back to position to fullyclose the orifice of presented since many minor mechanical changes may be lncorporated therein w1thout departure from the substance and essence of the invention and without the sac rificeof any of its substantial benefits and advantages.

I claim: In an appliance of the character described, the combination of a container havlng a pouring aperture in its wall at one end through which its contents may be delivered, and a slide adapted to'open and close saidaperture bearing flat against the'outer face of the apertured wall and having end portions overlying said outer face of the wall at the opposite margins of said apertureand having intermediate portions extended through the aperture lengthwise the latter and the slide to cooperate with the longitudinal edges of the aperture and bent in opposite directions to underlie saidwall 1 at the opposite margins of said aperture.
